In the section "Monitor", do I need to replace Identifier name by the right name of my screen and my TV? if yes, where I could find the exact name of my laptop screen and my TV.

I am using xfce4.10. By default, it can detect my TV and can display my desktop. but the laptop desktop covers the TV and they use the same screen. I would like they use two screen seperately just like under Windows and when I move my mouse to the right, it can enter to the TV desktop.
